instead of buying an aftermarket 4l60e to hold high hp could i just get mine rebuilt to hold the hp? the will be pushing 600 after its built, and i plan to run nitrious later. anywhere from a 100-250 shot. 250 shot only a few times at the track just to see the times.

 

Effectively yes ... since there really is no such thing as an AM 4l60E ... they are all stock 4l60Es that have been rebuilt, that's why there is a core charge.
